Define Documentation

#define readbyte (  x    )     (*(volatile unsigned char *)x)

reads one byte from memory location x. Definition at line 120 of file cubeos.h. Referenced by DUART_duart, FBIN_make, FBIN_set, and QSM_init.

#define readint (  x    )     (*(unsigned int *)(void *)(x))

reads one int from memory location x. Definition at line 124 of file cubeos.h.

#define readshort (  x    )     (*(unsigned short *)(void *)(x))

reads one short from memory location x. Definition at line 122 of file cubeos.h. Referenced by _QSM_sci_dis_rx, _QSM_sci_dis_tx, _QSM_sci_en_rx, _QSM_sci_en_tx, _QSM_sci_txbyte, FLASH_bcopy, FLASH_init, I2C_init, KERN_exphandler, KERN_panic, KERN_softreset, QSM_sci_int, QSM_sci_rxchar, RCJ_init, RG_init, and SPI_init.

#define readshortpos (  x, mask, pos    )     ((readshort(x)>>(pos))&(mask))

reads some bits of y to memory location x. readshortpos(x,mask,pos) reads memoy location x, shifts it pos bits right and masks the remaining bits with mask. example: readshortshortpos(TPU_CFSR3,0xf,0x8) reads the function code (4 bits wide, so mask 0xf) out of the TPU channel function select register of TPU Channel 2 (bits 8-11) Definition at line 149 of file cubeos.h. Referenced by getRCD.

#define writebyte (  x, y    )     *(unsigned char *)(x) = y

writes one byte y to memory location x. Definition at line 121 of file cubeos.h. Referenced by clearRRXSEL, clearRTXSEL, DUART_duart, FBIN_make, FBIN_set, init_LED, LED_OFF, LED_ON, QSM_init, setRRXSEL, setRTXSEL, and SPI_newcommand.

#define writeint (  x, y    )     *(unsigned int *)(x) = y

writes one int y to memory location x. Definition at line 125 of file cubeos.h. Referenced by _KERN_initcontext.

#define writeshort (  x, y    )     *(unsigned short *)(x) = y

writes one short y to memory location x. Definition at line 123 of file cubeos.h. Referenced by _QSM_sci_dis_rx, _QSM_sci_dis_tx, _QSM_sci_en_rx, _QSM_sci_en_tx, _QSM_sci_setbps, _QSM_sci_txbyte, _settimeofday, FBIN_make, FBIN_set, FLASH_bcopy, FLASH_init, I2C_init, KERN_exphandler, KERN_init_ptimer, KERN_panic, KERN_softreset, QSM_init, QSM_sci_int, QSM_sciinit, RCJ_fast, RCJ_init, RCJ_slow, RG_init, settimeofday, SPI_init, SPI_resetcmd, and TPU_init.

#define writeshortpos (  x, y, mask, pos    )

Value: writeshort(x,(readshort(x)\ &(~((mask)<<(pos)))) \ |(((mask)&y)<<(pos))) writes some bits of y to memory location x. writeshortpos(x,y,mask,pos) masks y with mask, shifts it pos bits left and masks the remaining bits into the memory location x. example: writeshortpos(TPU_CFSR3,0x9,0xf,0x8) writes function code 0x9 (4 bits wide, so mask 0xf) into TPU channel function select register for TPU Channel 2 (bits 8-11) Definition at line 136 of file cubeos.h. Referenced by KERN_init_ptimer.

Function Documentation

void init_LED (    )  [inline, static]

init control of the CUBE-II onboard status LED. This reconfigures the Port E of the mc68332 so that one bit is used for output. Definition at line 156 of file cubeos.h. References SIM_DDRE, SIM_PEPAR, SIM_PORTE, and writebyte.

void LED_OFF (    )  [inline, static]

switches the CUBE-II onboard LED off. Definition at line 169 of file cubeos.h. References SIM_PORTE, and writebyte. Referenced by FLASH_bcopy.

void LED_ON (    )  [inline, static]

switches the CUBE-II onboard LED on. Definition at line 163 of file cubeos.h. References SIM_PORTE, and writebyte. Referenced by FLASH_bcopy.
